3 Claims.

This invention relates to the construction of a barrel or container adapted for a variety of uses but more particularly intended for the purpose of containing and transporting explosives,

' chemicals and beverages.

- Another object of the invention is to provide a container with shock absorbing means sur- 16 rounding its contents, thus adapting the container for the shipment of' explosives of the kind which need to be safeguarded against being exploded by percussion.

A still further-object of the invention is'to furnish the container with means to surround its contents which is of a yielding resilient nature in order that internal pressure from the contents of the container will be less apt to rupture the wall thereof at any point.

:5 Although the invention is illustrated as applied to.a container of a barrel shaped or drum shaped character, yet it is to be understood that, broadly considered, the construction thereof may be applied to containers of other shapes than those 30 illustrated in the drawing.

Other objects, advantages and features of the invention may hereinafter appear.

right j Referring in detail to the drawing, in Figs. 1, 2-

ahd 3 is shown a drum shaped container having an outer cylindrical side wall 5 which will ordi-- 50 harily be made of sheet metal, and a cylindrical side wall 8 in inwardly spaced relation to said wall 5 and preferably also made of sheet metal. The space between these two walls will be filled with a suitable heat insulating material 'I such 5 as mineral wool or asbestos.

One end of the container is provided with a fixed head or closure member 8 and the other end thereof 'is provided with a removable head or ,closure 'member 9. The closure member dis furnished with an outer sheet. metal wall it which has an outwardly directed cylindrical flange H which is fitted tightly within the adjacent endportion of the cylindrical outer shell or wall 5. The end portion of this wall 5 and the edgeportion of the flange ii are crimped together at i2 in a well known manner to form an effective fluid-tight connection.

An important feature of the invention consists in various shock absorbing insulating means which are interposedbetween the inner and outer walls. One of these elements consists of an annular rubber ring i3. which is seated upon the inner surface of the end wall iii and is held in place between an annular outer angle iron flange i4 and a cooperating inner annular angle iron flange i5, these angle iron flanges having their foot portions welded or otherwise secured to the inner side of the end wall ill. Said rubber ring i3 is provided along the midwidth of its inner face with a trough or depression it within which is seated the adjacent end portion of the inner sheet metal member 6 and within which is also seated the outwardly directed cylindrical flange ll of an inner head or wall i8 which is in spaced relation to the wall Ill of the head 8. The space between the walls l0 and i8 is likewise filled with insulating material it such as mineral wool or asbestos.

In the drawing the containers shown are adapted to contain and dispense a beverage. A bung hole 2i is therefore provided, this bung hole being surrounded by a metal sleeve 22 provided with an external outwardly directed flanged? which seats upon a fiber gasket 26. This gasket is of an annular character and is seated within an annular depression or groove 25 which is formed by depressing the adjacent part of the sheet metal wall 6.

The sleeve 22 is provided with a thick body portion which furnishes an inwardlydirected shoulder 26. This shoulder 28 seats upon a shock absorbing gasket 21 which is interposed between said shoulder and an internally threaded ring it which is loosely seated in an annular depression in the internal wall 6. Said ring 2% is provided with an outwardly directedbaseportmn or foot 29, and the wall 6 is provided with a deflected lip 30 thereby forming an annular recess to receive the foot portion of said ring 28. The metal sleeve 221s provided with a screw threaded inner portion which cooperates with the threads of the ring 28 in-order that when the part 22 is screwed into place the gasket 21 will be compressed bctween the shoulder 26 and the ring 24. Above and below the bung hole 2| are provided the steel reinforcing rings which firmly engage the outer surface of the inner wall 6.

In the lower portion of Fig. 3'is shown a spigot sleeve 32 which is flanged and cushioned in the same manner as the bung hole sleeve 22 and is therefore provided for the most part with the same reference characters. This sleeve, however, is provided with internal screw threads 93 to cooperate with the external screw threads of the spigot, not shown. A removable plug 34 is shown screwed into the opening of said sleeve 32 for the purpose of closing the opening during shipment.

Below the removable head 9 is located in considerably spaced relation thereto a permanent cross head or partition 95 which is provided with a central filling opening 36 surrounded by an internally threaded sleeve 31 and furnished with a screw threaded closure cap 39. In the space between said head and the removable head 9*is located the ice or other refrigerating chamber 99. When said head 9 is in place it is confined to the space circumscribed by the side wall of the barrel. Said wall, in fact, projects slightly beyond the outer face of said head thus protecting the head from injury during all rolling and dropping movements wherein that end of the barrel may come into contact with a supporting surface.

To the inner face of the removable head 9 is secured a housing member 40 which is shown constructed as a sheet metal disc having around it a flan e 4| which is directed toward and seats ates with an upon t e inner'surface of the head 9. This housing member 46 is shown secured to the head 9 by a plurality of screws 42'furnished with nuts 49. In the space between the member 40 and the head 9 is stuffed a filling 44 of asbestos or other heat insulating material. The fixed partition 36 is located a sufficient distance from the head 9 to provide room for said filling without making the refrigerating chamber 99 too small.

The'removable head 9 is furnished with a handle 45 and m'ay, with respect to its other details, be of any suitable, well known construction. In Fig. 2 is shown in detail the preferred clamping means wherein an inner tapered lug 46 cooperouter tapered lug 41. Said head 9 is thus removably seated within the depressed part of the internal annular flange 48 of a rim member 49 which at overlies and is crimped to the peripheral portion of the adjacent end of the container.

The floor portion 5| of the rim member 49 terminates internally at the riser ring or flange 52. Around said flange 62 is placed the rubber ring 69 said ring having cut into its lower side a. kerf which receives the upper edge of the flared end portion 54 of the internal wall of the container.

By the construction described, owing to the clamping and crimping fits between the outer cylindrical wall and the outer walls of the'heads 8 and 9, the entire outer wall structure of the device is rendered rigid and inelastic; but the inner wall section is cushioned off from the outer wall section in such a manner that whatever substance is contained within the device is considerably protected from shock and vibration during transportation and handling. In the structure illustrated the cylindrical portion of the outer wall is provided with externally projecting beads Ill extending therearound. These beads are adapted to engage any floor or flat surface upon which the container shown in Fig. 1 may be rolled during handling.

In Fig. 4 is shown a modification wherein the container is of a barrel shape being provided with a bulged outer side wall member 60 preferably made of wood, the inner side wall member 6| desirably being made of sheet metal. The space between the members 69 and SI is stuffed with a filling 62 of mineral wool, asbestos'or the like. In the form of the invention shown in Fig. 4 there is also, at the filling end of the receptacle, an internal head or fixed partition 63 furnished with a filling sleeve 64 which is internally threaded to receive a screw cap 46. The removable head 66 thus forms the outer wall of the refrigerating chamber 61. This form of the invention shows a barrel provided both throughout the circumferential extent and at its ends with an exterior wooden wall spaced within which is a metal wall the space between the two walls containing insulated stuffing material. Both forms of the invention are also provided with a refrigerating chamber at the filling end of the container.

Describing further the form of the invention shown in Fig, 4, the construction, like that of Fig. 1 is provided along the inner faces of the end members with annular shock absorbing members |3a and 690. with regard to the shock absorbing member |3a the downwardly directed flange no of the lower metal plate I, is seated, under pressure, upon the member |3a while the adjacent end of the inner barrel wall- 6| abuts against said flange Ha and also has its edge portion in forcible contact with said shock absorbing member "a. At the upper end of the barrel the upper edge of the wall 6| abuts against a flange 63a with which the partition 63 isprovided and said wall and flange have their edge portions forcibly engaging the shock absorbing ring 53a. Preferably the various shock absorbing rings used in both forms of the invention will be formed of a compressible but firm rubber. Where the edges of the metal plates shown in the drawing forcibly engage this elastic material, depressions will be formed whether or not any groove is previously provided to receive the metal edges of the parts which are stabilized by the shock absorbing rubber elements. a

So far as the closure head of the barrel shown in Fig. 4 is concerned such of the details thereof as have not been specifically described may be of any well known preferred construction. The wood or similar material of which the side wall of the barrel will ordinarily be constructed, will of itself serve to a considerable extent as a shock absorber. In some respects it will protect the underlying structure more efilciently than would a metallic outer wall.

I claim:
